My invention relates to improvementsin anchors for marine use and the object of my invention is to improve the construction and increase the efficiency of anchors of this nature and to provide an anchor which will have a greater holding capacity in proportion to the weight of the anchor.

Another object is to provide an anchor of this nature which is less liable to be moved by a slow, step by step, movement commonl-y called walking of the anchor.

A further object is to provide anchor means in which more than one anchor memher is carried on a single anchor stock and in which the weight is thus more evenly distributed throughout the length of the stock so that the anchor will have a greater holding power in proportion to its weight.

- Another object is to provide a simple and efiicient way for increasing the weight of old anchors which are already in use by securing an'additional or secondary anchor member onto the stock of the said old anchor.

Other and more specific'object's will be apparent from the following description taken in connection with the accompanying draw- IIIO'S.

l lnchors of the-so-called star or mushroom type are extensively used for anchoring floating fish traps of the form used in Alaska-n waters for catching salmon and other salt 'watenfish. These anchors are usually large and heavy andoften weigh as much as six tons. These anchors are required to hold'the heavy floating traps in the same locations for long periods of time, often in rough weather, and it has been found that where a star or mushrooinanchor is placed on the rear end of a stock of'substantial'length there will often be a tendency for the anchor to'move or to walk due to the pull on the line veering slightly from side to side or due to raising and lowering of the forward end'of the anchor stock.

In accordance with my invention, I provide an additional anchor member on the forward" end of the anchor'stock which holds the forward end of the stock down and prevents lifting and sidewise movement of the same, thus allowing the rear anchor to hold with greater efficiency so that walking of the anchor is prevented. I I

Referring to Figs. 1 and 2, I show an anchor stock 15 having a larger star shaped anchor 16 seated on an expanding portion 17 at the rear end of the stock and secured thereon by means of a clamp 18. Another anchor 19 is seated on a taper =20'iiear the' front end of the stock and secured thereon by means of a clamp 21. Keys 22 may be used to prevent rotary movement of anchors 16 and 19 on the stock. A line or cable 23 is secured to the forward end of the stock. The anchors 16 and 17 are shown as six point star type anchors but they may be ofvarious other forms as shown in succeeding figures, or may have any number of points.

.- In Figs. 3 and 4 I show a mushroom shaped anchor 24 mounted on the forward endof an anchor stock 15, it being understood that the stock has another. anchor-mounted onit-s rear end. The anchor 24 may be left free and rotatable on the shank, as shown, or it may be keyed thereon in the same manner as the anchors 16 and 19. r r

In Fig. 5 I have shown a smaller anchor 25 mounted on the rear end of an anchor stock 15 and a larger anchor '26 mounted on the forward end of said anchor stock. This allows the anchor stock to assume an upward incline from rear to-front end, which incline may correspond to the general of pull of an anchor line or cable 27. This makes it -pos-.

sible to allow the anchor line to pull upward at a greater angle relative to the horizontal without lifting the forward end of the stock than would otherwise be possible, thus makingit possible to use less anchor line with this type of anchor.

In Figs. 6 and 7 .Ihave shown a duplex anchor of one piece construction embodying a rear anchor 28 and a front anchor mem ber 29. These anchors are each shown to be of four point construction but may have more or. less points if desired. The construction of this anchor member is essentially strong and heavy throughout and the front end of the anchor is preferably inorc massive than the rear end of the same. A short shank 30 is provided on the front end to which an anchor line may be secured- In'Fig; 8 I show thefrontend of an anchor stock 15 as provided with a weight 31 to hold the front end of'the stock. down when a pull is exerted thereon. This weight 31 is not an anchor itself but serves to increase the efficiency of the anchor not shown, on the rear stock down.

end of the stock by holding the stock down.

In Fig. 9 I show a duplex anchor constructed in which an anchor line 32 is connected with an anchor stock 15 between two anchors 33 and 34. The connection is preferably made by a clip or clamp 35 within which the anchor stock is free to rotate and said clip is preferably positioned closer to the front anchor than to the rear one.

Fig. 10 shows three anchors 36, 37 and 38 of gradually increasing size mounted on an anchor stock 15. These anchors may either increase in. size-from the rear to the front end of the stock, as shown, or they may be arranged in the reverse manner.

In Fig. 11, I show-two anchors 39 and 40 mounted on separate pieces of stock 15 and 15 respectively, which pieces of stock are connected with each other by link means 41.

In this construction the two anchors both cooperate to resist pull on the anchor line" but said anchors are more free toassume difier: ent inclinations and positions on rocky bottoms than when they are both secured to one solid anchor stock.

Fig. 12 shows a modified form of the in"- vention in which a single anchor member 42 is provided on a stock 43 and a relatively large heavy stock portion 44 extends rear- ..Wardly from the anchor member 42..

Fig. 13 shows the head of a star type anchor 45 which is not a true star but may be a generally elliptical irregular'shape with points projecting outwardly therefrom. This anchorhead may be usedin place of any of those hereinbefore described. On a. slopingv bottom it has less tendency to roll than a star anchor.

InFig. 14, I show an anchor bar 45 which may be "used on the front end of an anchor stock to furnish weight to hold the. anchor V This anchor bar, is. provided with flukes 47 at the ends which will engage wit-h. and dig into the ground or ocean bed thus offering resistance to a pull. i

. These anchors are all constructed so as to provide more weight on the forward. end ofthe stock thus affording means for holding down-the front end of the anchor stock which causes the anchor on the rear end'of the stock to dig in more-efiiciently and which prevent-s walking movement of the rear anchor and which adds its holding power to that of the rear anchor.

An important use for this invention found in rebuilding star anchors which are already .in use and which have been found which istoo light and place another anchor on the forward end of the anchor stock.

When this is done I preferably replace the clamps 18 by rings 48, as shown in-Figs. 3

and 4. These rings are secured to, the anchor stock by set screws 49 which may be tightened int-o punch marks or indentations made in the anchor stock. This constitutes efiicient means for securing the anchor to the stock by the use of the simplest tools which are always available.

The foregoing description and accompanying drawings clearly disclose a preferred embodiment of my invention but it will be understood that this disclosure is merely illustrative and that such changes may be made as are fairly within the scope and spirit of the following claims.

I claim:

1. In an anchor, a stock, a star shaped anchor member adjacent each end of said stock, said anchor members being of different size, both of said anchor members being dished on the side toward the same end of said stock and a line connected with the end of said stock toward which said anchor members are dished.

2. In an anchor, a stock, a star shaped anchor member on the rear end of said stock, means for securing an anchor line to the front end of said stock, and another star shaped anchor member on said stock adjacent the front end, but to the rear of said line securing means, said two anchor members being dished in the same direction and each of said star shaped anchor members having three or more points whereby two or more points of each anchor member will engage the ground at one time.

3. In an anchor, a stock, a star anchor member on the rear end of said stock, another star anchor member on the forward end of said stock, and an anchor line connected with the forward end of said stock in front of said last named anchor member, both'of said anchor members being concave on the side toward the front end of said stock.
